It's fantastic with both alerting *AND* trending. Plus, the data is malleable into other forms for custom reporting, etc. The only issue I've found thus far is *current* documentation is quite lacking.

If you find anything that is really good at this, please post the info. Will do, sounds like I'm doing a bake off of SNMP trending tools :) The thing I'm particularly interested in is a way to aggregate values across fairly dynamic groups: total interface traffic across a set of routers or switch ports, tcp connection counts across a set of host interfaces, etc. And I want to track the history of the aggregate trend for the groups even when the members come and go and the numbers in the group vary. Most of the things I've seen so far only deal with individual entities and if they understand groups at all, they don't maintain the history of the aggregated values when the members change. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Pretty much all of the packages that collect values and graph them use rrdtool as a component to store and graph the time-series data. OpenNMS has a pure-java alternative called jrobin that is theoretically more effecient as its default, but it can also be configured to use rrd if you want. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
